-------------------------------------

             Summary: Save one call to KeyValueHeap.peek per row
                 Key: HBASE-14315
                 URL: https://issues.apache.org/jira/browse/HBASE-14315
             Project: HBase
          Issue Type: Bug
            Reporter: Lars Hofhansl


Another one of my micro optimizations.
In StoreScanner.next(...) we can actually safe a call to KeyValueHeap.peek, which in my runs
of scan heavy loads shows up at top.

Based on the run and data this can safe between 3 and 10% of runtime.
